This invention relates to imlirovements 1n gearing and consists of the matters hereina l'ter described and more particularly pointed ont in the appended claims.

The invention is shown as applied to a washing machine of the kind including a tub and an operating shaft depending i'nto the tub and carni/'ing at its lower end a pounder to which itl imparts both a vertical and a rotary reciprocation. My improved gearing is nsed 'for the purpose o1 actuatingr the said operating shaft.

In the drawings:.#Figure 1 is a view representing a trent elevation of a washing machine ofi the kind described provided with mv improved gearing. the tub being partiallj.T shov'n in vertical section. Fig. Q is a top plan view of the saine. Fig. 3 is a view repref-:cnting on an enlarged scale a vertical section through a part of the n'ieehanism taken in the plane ofthe operating` shaft. Fig. 4 is a View representing a vertical Section through Fig. 3 in theplane indicated by the line 4-4f thereof. Fig. 5 isa View representing;- on an enlarged scale a horir/.ontal section tl'irough Fig. 1 in a plane indicated by the line 5 5 thereof. Fig. G is a -view similar to Fig. 5. showing a` slightly modified form of construction. Fig. 7 is a vien' representing a vertical section through Fig. G in a plane indicated by the line 7 7 thereof.

Referring now to that embodiment of my invention shown in the drawings. particularly in Figs. 1 to 5. inclusive. 10 indicates a support, in this case a washing machine tubhaving legs 11. Said tub. as shown` is square in cross-section and is provided with a lid 1'2 which is hinged to the fixed margina] top wall 12L1 of said tub. 13 indicates an operating shatt which is capable of both a longitudinal and of a rotary reciprocation itslower, end a pounder 14- ot familiar con!- struction.. The shaft 13 is mounted cen Vtrally of the tubin standard consisting of aA base-plate 16 attached to the tub lid 12 and ot' an upright overhanging arm 17'. The overhanging part of said arm and trie base 16 in vertical alinement below it, are provided with suitable apertures or openings in which the shaft 13 has bearing, so es to be capable ot' vertical reciprocating movement and rotary reciprocating movement. 1.8 in dicates a shaft located in a plane with the shaft 13 and extending at an angle to said shaft 13. The inner end of the shaft 18 is spaced from the shaft 13. Said shaft is, in this case, horizontal and 'is mounted in bearingstormed in horizontaliy spaced nptulerumed on a stud 23 tilted to a plate 24.

Said plate 241 is attached to the fixed marginal top Wall 12a of the tub. The said gear Q0 meshes. asshown herein, with a pinion 25 fixed to the hub of a ily-Wheel 26 which is jonrnaled in any convenient manner at the side oit the tub. Thns the gear 520 may' be rotated by means ot a suitable handle attached to the {1y-Wheel l(not shown) or may be operated as a partof a high-speed niet-,hef nism by means o t the lever 22,-the oscillation of the lever'imparting continuons; rotary movement to the gear Q0 and to the iiywheel 26 which acquires momentum and thus facilitates the operation of the mechanism. The means interposed between the continuously rotating actuating;` member. in this case the. shaft 18 and the operating member capable of rotary reciproeation and oi' reciprocation in a line parallelto its axis of rotary reciprocation. in this ease the shaft 12. tor transposing the movement of the tirst into the movement of the second is as tollows: 27 indicates an arm fixed to and movable with the shaft- 13 located intermediate the bearing openings in the overhanginfr arm 17 and the base plate 16 and extending toward the shaft 18. 31 indicates a crank-arm fixed` to the inner end of the shaft 18. There "is interposed between the crank-arm 3l and the arm fixed to the opother machines where a similar movement is erating shaft 13, operating connecting required.

means including a pin made rigid With the one arm and-a device carried by the other arm which provides for relative rotary and longitudinal reciprocatory movement of 'said pin. with reference to said other arm.

As shown herein in Figs'. 1 to 5, inclusive,

at the end ofthe arm 27 fixed tothe shaft 13.

vided With vertical threaded apertures into which are screwed screws 29 which have shoulders for engagement With the outer faces of said block and have shouldered formed in the bifurcations of the arm 9.7.

The crank-pin 30 has in this case rotative and longitudinally reciprocatory bearing in 31 imparts an up and down movement to thevarm 27 fixed to the operating shaft and also a rotary reciprocatory movement to it and the said arm in turn imparts to the op- '3U erating shaft 13 at once a vertical reciprocation and a rotary reciprocation. The diameter of the arc described by the crank-pin represents the amount of the vertical reciprocation and also the chord of the aro through which the shaft is rotated.

In Figs. 6 and 7 I have shown a slightly vmodified construction. In these views 32 indicates the bifurcated arm fixed to the operating shaft, and 33 the crank-pin. 34, 34 indicate horizontally spaced vertical rods secured to and extending between the bifurcations of the arm 33, said rods being spaced apart a sufficient distance to allow for the required inovement of the crank-pin in imparting the intended amplitude of oscillation to the arm 32. A s shown, the rods 34 are preferably provided With rotative antifriction sleeves 35 and the crank-pin is like- Wise provided with an antifriction sleeve 36. The operation in this case is the saine as in the other case.

My improved gearing is very simple and eiiicient for the purpose intended and, as will be readily apparent, may be applied to l l l l l l i v the pin is in the'form of a crank-pin 30 car- ;k ried by the crank-arm 3l and the bearing device for the pin is a block 28 bored to receive said crank-pin and rotatively mounted While in describing my invention I have referred to certain details of construction and arrangement of parts, it is to be understoodrth at my invention is inno way limited thereto except in so far as may be pointed out in the appended claims.

I `claim as myinvention 1.v ln combination with an operating shaft capable of both vertical and rotary reciprocation, a continuously rotatable, horizontal 5 shaft, in a plane with said operating shaft The axis of rotation of said block is vertical and the end of the arm 27 is bifurcated to receive the same. Said block is proand having` one end spaced therefrom, a crank-arm fixed to that end of thesaid horizontal shaft, a horizontal Icrank-pin fixed to said crank arin and extending toward said operating shaft, a horizontal radial arm l fixedto said operating shaft and extending 'toward said horizontal shaft, said arm being heads loosely mounted in suitable -apertures 1 bifurcated at its end to provide verticallyI spaced parallel, vhorizontally extending bearing surfaces` and means operatively connectl ing` said crank-pin with said arm providing .the block 28. The rotation 4of the crank-arm i for rotative and horizontal reciprocatory bearing'of said crank-pin between said bearf ing` surfaces. l A y Q. ln combination with an operating shaft capable of both verticaland rotary reciprocation, a continuously rotatable, horizontal shaft in a plane with said operating shaft and having` one end spaced therefrom, a crank-arm xed to that end of the said horizontal shaft, a horizontal crank-pin fixed to said crank arm and extending toward said operating shaft, a horizontal radial arm fixed to said operating shaft and extending toward said actuating shaft, said arm being liifurcated at its end to provide vertically spaced, parallel, horizontal bearing surfaces. a block having bearing between said bearing surfaces, and means providing vertical journals for said block adapting it for rotary -oscillatory movement about a vertical axis.

said crank pin havingrotative and horizontal reciprocatory bearing in said block. In testimony, that I, claim the foregoing;r
